The Celestial Pearl Danio, scientifically known as Danio margaritatus, is a small, stunning freshwater fish belonging to the Cyprinidae family. Discovered relatively recently in 2006, this species is native to small, shallow, and vegetated ponds in Myanmar (Burma). Its striking appearance, characterized by a dark blue body adorned with iridescent, pearl-like spots and bright red or orange fins, has quickly made it a popular choice among aquarists. Celestial Pearl Danios typically grow to about 1 inch (2.5 cm) in length and have a lifespan of 3-5 years in captivity when provided with proper care.
Habitat and Tank Requirements:
In their natural habitat, Celestial Pearl Danios are found in shallow, clear water bodies that are heavily vegetated. The water in these environments is usually soft and slightly alkaline. To replicate these conditions in a home aquarium, it’s important to provide a tank with suitable water parameters and an environment that mimics their natural setting.
Tank Size and Water Parameters:
| PARAMETER | RECOMMENDED |
|---|---|
| Tank Size | Minimum 40 litres |
| Temperature | 72-79°F (22-26°C) |
| pH | 6.5-7.5 |
| Hardness | Soft to moderately hard water, 1-8 dGH |
This table provides the optimal water conditions for keeping Celestial Pearl Danios healthy and displaying their vibrant colors. These fish thrive in well-maintained tanks with stable water parameters, mimicking the conditions of their natural habitat.
Celestial Pearl Danios thrive in tanks with a soft, fine-grained substrate, such as sand or smooth gravel, which is gentle on their delicate bodies. The tank should be densely planted with live plants, including both foreground and background varieties, to provide ample hiding spots and simulate the lush vegetation of their natural habitat. Floating plants can also be used to diffuse light and create a more subdued environment, which these fish prefer. A gentle filter is recommended to maintain water quality without creating strong currents, as these fish are accustomed to calm waters.
We Recommend:
These carefully selected options provide a well-balanced nutritional profile, ensuring that your fish receive the essential nutrients they need for optimal growth, vibrant colors, and overall health. By offering a variety of these high-quality foods, you can help maintain the vitality and well-being of your fish, promoting a healthy and thriving aquarium environment.
Behavior and Compatibility:
Celestial Pearl Danios are peaceful, schooling fish that are best kept in groups of at least 6-8 individuals. They are known for their shy and sometimes timid nature, especially when first introduced to a new environment. However, when kept in larger groups and provided with plenty of hiding spots, they become more confident and exhibit their natural behaviors. These fish are excellent companions in community tanks, coexisting well with other small, non-aggressive species such as small rasboras, tetras, and dwarf shrimp. However, they should not be housed with larger or more aggressive species that could stress or prey on them.
